CARBlD-CARTRIDGE FOR-ACETYLENE GAS.

SPECIFICATION forming part of Letters Patent No. 610,171, dated September 6, 1898.

Application filed June 16, 1897. Serial No. 640,981. (No model.)-

' of the city, county, and State of New York,

have invented a certain new and useful Improvement in Oarbid-Oartridges, of which the following is a specification.

The present invention relates to a new form of carbid-cartridge.

In the generation of acetylene gas in small quantities, as for supplying a portable lamp where the generating apparatus is located inside the lamp, it has been customary to make the carbid in the form of a cartridge, the masses of carbid being bound together by some suitable binding medium, as paraflin or the like. Where these cartridges have been made of a substantially cylindrical or square shape and water has been supplied thereto, the resulting refuse accumulates to such an extent that after use for a short length of time it is impossible for the small quantity of water needed to generate the small quantity of gas to reach any of the carbid which has not been decomposed.

The present invention is intended to obviate this difficulty.

In the drawings I have shown a cartridge which embodies my invention, in which Figure 1 is a View in perspective, and Fig. 2 is a vertical section showing the manner of supplying water to the carbid.

material whether the cartridge is of the inverted-cone-frustum shape shown in the drawings so long as the cartridge has sides which converge from the upper surface to the base. A cartridge of the form of an inverted truncated pyramid, for instance, would have the same advantages. made according to the present invention is placed in position, as shown in Fig. 2, and water isapplied, as from a water-supply 4, to the upper surface of the cartridge, the refuse lime gradually falls over the sides of the car,- tridge and banks up against the downwardlyconverging sides of the cartridge. In this way the refuse is disposed of in such a manner as not to interfere with the penetration of the water to the carbid which has not been acted on. The carbid-cartridge is, as shown, entirely self-supporting and is unprovided with any external casing in contact with. its
